History Main / EggMacGuffin

Usually the baby is a SidekickCreatureNuisance(though it may actually be a gargantuan creature with the mind of a small annoying one) [[ObliviousAdoption that thinks the first person (usually the discoverer) it sees is its "mama".]] Usually the baby may be far too much for the character to handle and they have to somehow find its real parents. A common variant has the egg hatching into something evil.

* In the ''Literature/{{Leviathan}}'' trilogy, there is a very mysterious Egg Macguffin in the first book. [[spoiler:In Behemoth, the sequel, the egg hatches, and a SmallAnnoyingCreature is introduced in the form of Bovril. Bovril latches onto Alek and they become [[{{ABoyAndHisX}} A Boy and His Rapidly Learning Skunk Thing.]]]]

* ''WesternAnimation/TheLandBeforeTime'': The final series episode has the gang needing to work with the older dinos who tend to bully them in order to move a nest of Sharptooth eggs farther from the Great Valley so the predators will be less of a threat.

* The second ''Franchise/TheLandBeforeTime'' film has an egg stolen from Ducky’s family by egg-eating dinosaurs. Littlefoot and the group go after it and get it back only to find that the Swimmer egg is already back in the nest. They make a nest for the mystery egg and it hatched into Chomper, a baby Sharptooth. After initially being afraid of him, he later goes on to become a regular group member in the TV series.

* In Myth/OceanianMythology, [[PlayingWithFire Pele]] carries an egg from her original home in Tahiti to the Hawaiian archipelago. The egg hatches out her fully-formed sister [[NaiveEverygirl Hi'iaka]].

* The entire plot of ''Anime/MoribitoGuardianOfTheSpirit'' occurs because Prince Chagum is carrying the egg of a water spirit within his body, at first leading many people to believe that he's [[DemonicPossession possessed by a demon]]. The entire cast becomes very concerned both with making sure the egg hatches successfully (since there will be a horrific drought if it doesn't) and with making sure that Chagum isn't killed in the process, with much of the drama of the latter half of the series coming from the fact that the two goals may be mutually exclusive.

* In Creator/DataEast's ''Pinball/JurassicPark'', cracking open dinosaur eggs award various bonuses.

* Played with in the ''Anime/KirbyOfTheStars'' anime, where the giant steel bird Dynablade lays an egg that later disappears, with fragments of its shell around. The other characters suspect that Kirby has eaten the egg, and [[MamaBear Dynablade ain't happy...]]

* In Hawaiian mythology, [[PlayingWithFire Pele]] carries an egg from her original home in Tahiti to the Hawaiian archipelago. The egg hatches out her fully-formed sister [[NaiveEverygirl Hi'iaka]].

Despite the trope name, the egg itself does not necessarily need to be a MacGuffin. The trope's name is a silly {{pun}} on Egg [=McMuffin=], the breakfast sandwich.

** Most of the cast members have received a Pokémon through this fashion. Ash received an egg with hatched into a Phanpy, and another one much later that hatched into a Scraggy, May received one that hatched into an Eevee, Brock received one that hatched into a Happiny, and Dawn received one that hatched into a Cyndaquil. This happens in the games quite a lot as well.

* In the short film ''Eiga VideoGame/{{Tamagotchi}}: Himitsu no Otodoke Dai Sakusen'', the item that Mametchi and friends have to deliver to the Gotchi King is a giant egg that's getting ready to hatch.

** In the ''Manga/PokemonSpecial'' manga, Gold receives the Togepi egg, which at one point nearly gets eaten by a wild Gligar. Thankfully, it hatched into a KillerRabbit with a gambling problem and took the Gligar down itself.
